ISX15 X2/X3 MY16 Engine Outlet NOx Sensor TRP for Out of Warranty Failures

After verifying that the engine meets the above requirements, perform the following actions:
1. As required, remove and replace the Engine Outlet NOx Sensor using service procedure 019463 in the appropriate Cummins Service Manual.

Note : If the unit is covered by a Cummins Base, Extended, or Emissions warranty
program, file claims as is appropriate and best benefits the customer. If Fuel
Pressure Regulator is covered by a warranty program, the unit is NOT eligible for
this field action. File Admin ONLY claim to close the field action.
Note : Certified repair locations outside of California, who elect to perform this
campaign on engines installed in vehicles which are registered in the state of
California, are authorized to do so if they have the two items noted below in their
inventory. Please note that the Label, Authorized Change and the Proof of
Correction Form must be ordered through standard parts processes. They
are not available on QuickServe® Online.
2. If applicable, a Label Authorized Change, Cummins part number 5297400, must be filled out
and affixed to the engine. Clearly print or type EONOx SENSOR UPDATE in the center box.
Fill in the Campaign Number, Distributor or Dealer Code, and Date information. Peel off the
backing material and install the label on the engine valve cover near the engine data plate.
There is a clear protective cover on this label; peel the backing off of this cover and push the
clear cover over the printed material. This will help protect the label during engine operation.
Label cost and appropriate SRT time can be claimed per Campaign guidelines.
3. If applicable, an Emissions Campaign - Proof of Correction form, Bulletin #4310621, must be
filled out and provided to the Customer. Inform the Customer to retain this certificate as proof
that the Emissions Campaign has been performed. This form may be required as proof of an
Emissions Campaign by the State of California, for vehicles registered in that state, the next
time the vehicle registration is renewed. Form cost and appropriate SRT time can be claimed
per the Campaign guidelines.
4. File one claim for the applicable listed parts and required labor to complete the repair.

Material Disposition
Where applicable, items removed should be returned to ReCon for core credit. Unless otherwise
indicated, items with no core liability can be scrapped.
